1. general description the tja1080a is a flexray transceiver that is fully compliant with the flexray electrical physical layer specification v2.1 rev. a (see ref. 1 ). in addition, it incorporates features and parameters included in v3.0.1 (see ref. 2 and section 14 ). it is primarily intended for communication systems from 1 mbit/s to 10 mbit/s, and provides an advanced interface between the protocol controller and the physical bus in a flexray network. the tja1080a can be configured to be used as an active star transceiver or as a node transceiver. the tja1080a provides differ ential transmit capability to the network and differential receive capability to the flexra y controller. it offers excelle nt emc performance as well as high esd protection. the tja1080a actively monitors the system performance using dedicated error and status information (readable by any microcontroller), as well as internal voltage and temperature monitoring. the tja1080a supports the mode control as used in nxp semiconductors tja1054 (see ref. 3 ) and tja1041 (see ref. 4 ) can transceivers. the tja1080a is the next step up from the tja1080 flexray transceiver ( ref. 5 ). being fully pin compatible and offering the same excellent esd protection, the tja1080a also features: ? improved power-on reset concept ? improved electromagnetic emission (eme) ? support of 60 ns minimum bit time ? improved bus error detection functionality this makes the tja1080a an excellent choice in any kind of flexray node. see section 14 for a detailed overview of differences between the tja1080 and the tja1080a. 2. features and benefits 2.1 optimized for time trig gered communication systems ? compliant with flexray electrical physical layer specification v2.1 rev. a (see ref. 1 ) ? automotive product qualificatio n in accordance with aec-q100 ? data transfer up to 10 mbit/s ? support of 60 ns minimum bit time tja1080a flexray transceiver rev. 6 ? 28 november 2012 product data sheet

[1] pin errn provides a serial interf ace for retrieving diagnostic information. [2] trxd lines switched as output if txen activi ty is the initiator for star-transmit mode. [3] trxd lines are switched as input if trxd ac tivity is the initiato r for star-transmit mode. [4] valid if v io and (v buf or v bat ) are present. pin bge must be high in order to enable the transmitter via pin txen. if pin bge is low, it is not possible to activate the transm itter via pin txen. if pin txen is not used (no controller connected to the transceiver), it has to be connected to pin gnd in order to prevent txen activity detection. in all normal modes pin rxd is connected to the output of the normal mode receiver and therefore represents the data on the bus lines. table 9. pin signalling in star configuration mode trxd0 / trxd1 errn [1] rxen rxd transmitter inh1 inh2 low high low high low high star-transmit output [2] input [3] error flag set error flag reset bus activity bus idle bus data_0 bus data_1 or idle enabled high high star-receive output disabled star-idle input star-locked input star-standby input error flag set [4] error flag reset wake flag set [4] wake flag reset wake flag set [4] wake flag reset star-sleep input float float
